The install took 2.75 hours, mostly because the bracket and bolt to hold the brake line extender (see picture) were interfering with the frame. The technician had to saw down the bolt, and move it around on the bracket to find a position that worked. After he got that squared away, and rerouted the cables (still original stock brake and clutch lines). The risers are completely installed now, and everything is operational, but the stretch is tight for the front brake line, even with the extender. I'll have to keep an eye on it. The handguards are close to hitting my tank, but they're okay....no rotating the handlebars to tweak my control positions! All in all, the parts are good quality and the setback is substantial....exactly what I was looking for. By the way, the tech told me that the instructions were basically useless. Good thing I took it to the BMW shop.
Looks great. I've never seen a brake line adapter like that but it looks like a clever way to handle length problems. If you still think it's too tight you can get an extended line from Speigler and when there is a scheduled brake service-flushing-you could change it then. As for the instructions, they were perfectly clear to the guy that wrote them!!! After you get a few rides in let us know how you like them.. Gary
